Summary

The purpose of the work was to monitor and improve the condition of the parodontum in case of dento-maxillary anomalies through carrying on a complex medicamentary orthodontic treatment. The study comprised 82 patients with different dento-maxillary anomalies, with average age of 13,98 ± 0,38 years and with the pitch between 8 and 22 years.

The investigation algorithm of the patients included: estimation in dynamics of the mouth hygiene – OHI-S index (G.Green, I.Vermillion, 1964); photographic exam; mode study; assessment of parodontal pre-, intra-, posttreatment orthodontic diseases through clinical endooral exam; determining of Parma gingivitis index (1960), index of papillary hemorrhage Mühlemann (1971); radiological orthodontic pre- and posttreatment exam; cytologic exam of the gum epithelium.

There were diagnosed parodontal diseases in 64 patients (78,05%) with dentomaxillary anomalies, while 18 patients (21,95%) had a healthy parodontum.

The orthodontic treatment was carried out with modern fixed appliances with slot .022" brackets, Straight-wire technique, Roth prescription with elements of individualisation – in 36 patients (43,9%) and with removable appliances (palatinal and lingual orthodontic plates) with mechanical and functional action – in 46 patients (56,1%). The parodontal therapy included topical administration of BioR medicine 0,1% gel in group I (of study), while in group II (of reference) – parodontal therapy with usual medicines (Григорьян А.С., Грудянов А.И., 2004).

The truthful obtaining of the posttreatment parodontal recovery presented different values depending on allegiance to the group – 73,8% patients in group I and 65,2% patients in group II and variety of the used orthodontic apparatus – in 80,8% patients treated with fixed appliances and 61,5% of those treated with removable appliances, this rendering supremacy to complex orthodontic treatment with fixed appliances.
